Convert existing binding to dtschema to support validation.

The binding has been renamed to match its compatible. Apart from that,
it is a direct conversion with no additions.

This could probably just go into trivial-rtc.yaml.

Does it make no difference if the reg property is a single address or
address + size? trivial-rtc.yaml does no specify that ('an address' is
mentioned), and I don't know if it is obvious for someone who wants to
use this device.

Best regards,

First, you can answer to this by yourself: where do you have the "size"
documented? You will see that nowhere, because your description is
actually redundant and should be dropped. So if "nowhere", then your
binding is the same as trivial-rtc.

The presence of size is defined by the bus, not by this binding.
Therefore you do not have to tell anyone that it is address+size,
because it is obvious from the bus. And from device datasheet (bindings
are not replacement of datasheets).

Best regards,
Krzysztof
